This app basically creates another xserver and virtualgl to direct the opengl calls into the xserver which can display on the intel framebuffer. This does require the nvidia driver, but also can work with nouveau. Running vdpau with this setup just results in errors.

OK, now I understand.  I haven't worked with the netbooks and MythTV.  The
systems I've been working with are "nettop" style machines.  It had not 
occurred to me that the netbook designs would connect the internal LCD monitor
to the Atom graphics subsystem and not the Nvidia chip.  My current Atom
system is a Jetway that uses the D525 (supposed to be a pineview series chip)
and ION2.

The information I've found suggests the Nvidia chip (and its
framebuffer) connects directly to the HDMI port on some (all?) of the 
netbooks using this set of chips.  Does it make a difference if you have
a monitor connected to the HDMI port (and the internal display turned off)?
